SECURITY DOOR I FIELD OF THE INVENTION The present invention relates to structural members,

and more particularly to doors having combinations of a grill, a window assembly and an opening center panel.

DESCRIPTION OF THE PRIOR ART Conventional ventilated doors and illuminated doors include windows and hingedly mounted center panels. Ventilated doors and illuminated doors must be employed in an architectural plan with care lest security of the building be sacrificed because windows and door panels carried in the door may be easily plied or broken open. Further, the owner who uses a ventilated door having movable windows or center panels, may invite unauthorized entry because the only material remaining in the center cavity of the door may be a fly screen. Accordingly, it is an object of the present invention to provide a door having a combination grill, window assembly and opening center panel.

It is further object of this invention that the window assembly be provided with suitably mullioned lights operable to be selectively opened and closed.

It is an object of this invention to provide a security door having suitably mullioned movable windows provided with fly screens and the like.

It is another object of this invention that the means mounting the drill window assembly and center panel to the door frame be suitably shielded to access from the outside of the door.

These and other objects shall become apparent from the description following, it being understood that modifications may be made without affecting the teachings of the invention here set out.

SUMMARY OF THE INVENTION The security door comprises a frame having a central cavity, a grill fastened to the frame, a window assembly including suitably mullioned window lights, and a hingedly mounted center panel, which are suitably mounted in a central cavity in the door frame.

A more thorough and comprehensive understanding may be had from the detailed description of the preferred embodiment when read in connection with the drawings forming a part of this specification.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a front oblique pictoral view of the security door of this invention in exploded view for illustrative purposes.

FIG. 2 is a front, outside oblique pictoral view of the security door.

FIG. 3 is a rear, inside oblique pictoral view of the apparatus of the FIG. 2.

FIG. 4 is a fragmentary cross-sectional view taken substantially along the lines 4-4 of the FIG. 3, shown with a hinge for illustrative purposes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings and more particularly to the FIG. 1, the security door of this invention is shown to advantage and generally identified by the numeral 10. The security door is intended to be hung in any ofa variety of commonly known doorjambs (not shown), including pre-hung type door jambs. The security door 10 comprises a frame 11, a grill frame 12, a grill l3, and a window panel assembly 14. The frame 11 is fabricated of structural metal sections, wood and other suitable material members to form a rigid, twodimensional structure having a central cavity 11'. The configuration of the outer perimeter edge, here shown as a rectangle, may be varied with its door jamb in response to demands of architectural design. Likewise, the configuration of the cavity 11, also shown as a rectangle, may be varied with the grill frame 12, the grill 13 and the panel assembly 14, according to demands of design. The frame 11 may be fitted with a lock and nob 15, and hinge recesses 16.

The grill frame 12 is intended to provide a mounting means for the grill 13 and the window panel 14, and a shield means to cover mounting fasteners. The frame 12 may be fabricated as a portion of the cavity 11, or as a separate frame structure or outside the frame 11 as shown in the drawings. As a separate frame structure, the grill frame 12 may be fabricated of channel 12' with a flange 12" disposed perpendicular to the legs of the channel 12', in a configuration similar to the cavity 11 as shown to advantage in the FIG. 4. The grill frame 12 is engaged with its flange 12" adjacent the cavity 11' with the channel 12' on what is intended to be the outside of the door 10. The fasteners may be disposed through the flange 12" or a middle wall of the frame 12 adjacent the interior of the cavity 11' into the material of the frame 11. It may be seen that the inside lip is operable to shield fasteners retaining the grill 13 and the window panel assembly 14 to be described hereinafter. The grill 13 comprises a lattice of rods 17 and a plurality of gussets 18. The lattice of rods 17 includes a multiplicity of rods and ornamental iron material disposed rectilinearly, transversely and diagonally across the area of the cavity 11', thus making the cavity 11' impassible. Wire mesh 19 may be welded to the rods 17 to further stiffen the grill 13. The rods 17 are fastened to the frame 12 by means of the gussets 18. As shown in the FIG. 2, the gussets 18 are fastened to the exterior walls of the channel 12. It is to be understood that the gussets 18 may be suitably fastened to the grill frame 12 on the interior or the exterior of the grill frame 12.

Referring again to the FIGS. I and 4, the window panel assembly 14 includes a sash 20 of a similar configuration to the interior configuration of the channel 12 of the grill frame 12, and a plurality of suitably mullioned lights 21 and 22. The sash 20 may be fabricated of suitable channel strip 20'. The lights 21 may be fixedly glazed into the sash 20. The lights 22 may also be vertically slidably mounted in the sash 20. The slidable lights 22 carried in mullion member 20 of the sash 20 and may be locked into position by suitably urged pegs engagable with suitably located spring loaded peg receiving holes (not shown). The window panel assembly 14 may also include screens 23 selectively slidable over the slidable lights 22. The screens 23 may be slidable in the manner of the lights 22 or may be detachable mounted in the sash 20. The window panel assembly 14 is intended to be disposed within the channel 12' of the grill frame 12.

The security door 10 may include a solid panel 24 of similar configuration and area to the cavity 11. The panel 24 may be fabricated of wood, metal and the like and is hingedly mounted at one of its terminal sides to the corresponding adjacent side of the cavity 11. The

panel 24 will be secured by a lock. As shown more clearly in FIGS. 3 and 4, in practice, it has been found to advantage to provide a back bar-like lock 26 comprising a tubular bar 26 hingedly mounted at one of its terminal ends to one side of the panel 24 and a latch 27 fastened at the terminal end opposite the hingedly mounted terminal end of the tubular member 26, and a latch bracket 28 fastened to the interior terminal edge of the cavity 11'. The bar 26' is fastened transversely across the midportion of the panel 24. The hingedly mounted terminal end of the bar 26' may be fastened at one of the center hinges 29 fastening the panel 23 to the frame 11. The latch 27 slides rectilinearly distally from the terminal end of the bar 26, and is urged toward the hinge 29 by a spring 30. The latch 27 includes a hook-like lug 31 which is operable to engage a hole 28 in the latch bracket 28. The latch 27 may be disengaged from the latch bracket 28 by disengaging the lug 31 from the hole 28' of the latch bracket 28. The panel 24 may be protected from damage due to careless opening of the door when the panel 24 is opened by a swing control bracket 32. The swing control bracket 31 is disposed distally parallel to one of the terminal ends of the panel 24. The bracket 32 includes a rectilinear slot 32 corresponding to a predetermined safe-travel distance. The panel 24 includes an upstandingly disposed bracket slide 33 which is operable to ride within the slot 32 of the bracket 32.

In operation, the panel 24 may be opened by activating the lock 26 as set out above. The lights 22 may be slidably activated in the sash as set out above. Thus,

operations may be performed without exposure to in trusion through the door 10.
